What do the plugs look like when you take them out? A choke that is
partially or fully closed, a mixture that is way too rich, or a
plugged air filter will foul plugs. Also, as a previous poster
pointed out, over filling with oil may too.

have an idea what might be going on? Appreciate the help.

are you adding oil to the gas?
